In order to unlock the achievement, the player must have completed all previous Easter eggs in the game and complete the main Easter egg in Revelations. It will then be unlocked alongside "For The Good Of All".

For completing the achievement, the player is rewarded with a staggering 1,000,000 XP (enough to prestige once or gain 18 levels if master prestige) and is given the "Primis Rulz" Dark Ops calling card. The RK5 is also given to the player as a new starting weapon alongside the Bloodhound in Shadows of Evil, the Mauser C96 in Origins, the M1911 in the Zombies Chronicles maps, and the MR6 (all of which get full ammo from the start) in all other maps.
